The review queue & spending caps
A per-expense cap keeps agent write access bounded and reviewable.
Set a cap when creating a key or approving a connection — $100 is a sensible default for a new agent. Anything above it is saved as pending_review, visible in Review, and excluded from totals and budgets until approved.
Approving or rejecting
A person can approve an item into totals or reject it. The agent that created it cannot perform this human-only decision.
For agents
pending_review is expected, not an error. Report it plainly and do not retry or split the expense to evade the cap.
